// The emacs-keys layout is a modified "us" layout:

//   * Left-Alt and Left-Ctrl are swapped
//   * Right-Alt and Right-Ctrl are swapped
//
// This could probably be pieced together from various
// rules that ship with xkeyboard-config, but it's a
// lot nicer to have everything available as a layout.
